Explanation Given information: The volume flow rate per unit width through the circle having a radius ( r ) is ∨ ˙ L . The source of the line is at the origin. The stream function which is along the x direction in positive direction is 0 . Here, the width is L and the volume flow rate is ∨ ˙ . The x axis and the y axis are dividing the circle in 4 equal parts which are given below. Positive x axis ( θ = 0 ) and positive y axis ( θ = 90 ° ) . Positive y axis ( θ = 90 ° ) and negative x axis ( θ = 180 ° ) . Negative x axis ( θ = 180 ° ) and negative y axis ( θ = 270 ° ) . Negative y axis ( θ = 270 ° ) and positive x axis ( θ = 0 ) . The volume flow rate is divided equally between them. Hence, the volume flow rate between positive y axis and positive x axis equals to the quarter of the total flow rate ( 1 4 ∨ ˙ L ) . This volume flow rate per unit width in between two stream lines becomes equal to the difference in the values for the two stream lines. Write the expression for the difference in values of two streamlines. ψ ( θ = 90 ° ) − ψ x ( θ = 0 ) = 1 4 ∨ ˙ L ........... (I) Here, the stream function along the positive y axis is ψ ( θ = 90 ° ) . The volume flow rate in between the negative x axis and positive x axis is equal to the half of the total volume flow rate which is given as ( 1 2 ∨ ˙ L )
